Senecio plant named ‘Sene Nirenago’

ABSTRACT

A new and distinct cultivar of Senecio plant named ‘Sene Nirenago’, characterized by its upright and uniformly mounded plant habit; vigorous growth habit; freely branching habit; freely flowering habit; and daisy-type inflorescences with ray florets that are deep violet and light reddish purple in color.

Botanical designation: Senecio cruentus.

Cultivar denomination: ‘SENE NIRENAGO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Senecio plant, botanically known as Senecio cruentus, and hereinafter referred to by the name ‘Sene Nirenago’.

The new Senecio plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new upright, uniformly mounding and vigorous Senecio plants with a freely-branching habit, early flowering and numerous attractive inflorescences.

The new Senecio plant originated from a cross-pollination conducted by the Inventor in March, 2016 of a proprietary selection of Senecio cruentus identified as code designation 16BonS-12-1, not patented, as the female, or seed, parent with a proprietary selection of Senecio cruentus identified as code designation 16BonS-12-2, not patented, as the male, or pollen, parent. The new Senecio plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in February, 2017.

Asexual reproduction of the new Senecio plant by terminal vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since October, 2018 has shown that the unique features of this new Senecio plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Senecio have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sene Nirenago’. These characteristics in combination distinguish ‘Sene Nirenago’ as a new and distinct Senecio plant:

-   -   1. Upright and uniformly mounded plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Freely flowering habit.     -   5. Daisy-type inflorescences with ray florets that are deep         violet and light reddish purple in color.

Plants of the new Senecio can be compared to plants of the female parent selection. Plants of the new Senecio differ primarily from plants of the female parent selection in ray floret color as ray florets of plants of the new Senecio are deep violet and light reddish purple in color whereas ray florets of plants of the female parent selection are dark red in color. In addition, plants of the new Senecio have larger inflorescences than plants of the female parent selection.

Plants of the new Senecio can be compared to plants of the male parent selection. Plants of the new Senecio differ primarily from plants of the male parent selection in ray floret color as ray florets of plants of the new Senecio are deep violet and light reddish purple in color whereas ray florets of plants of the male parent selection are dark red in color. In addition, plants of the new Senecio are shorter than plants of the male parent selection.

Plants of the new Senecio can also be compared to plants of Senecio cruentus ‘Sunsenegonana’, disclosed in U.S. Plant Pat. No. 28,266. In side-by-side comparisons, plants of the new Senecio differ from plants of ‘Sunsenegonana’ in the following characteristics:

-   -   1. Plants of the new Senecio are shorter and broader than plants         of ‘Sunsenegonana’.     -   2. Plants of the new Senecio are more freely branching than         plants of ‘Sunsenegonana’.     -   3. Plants of the new Senecio have shorter, narrower and darker         green-colored leaves than plants of ‘Sunsenegonana’.     -   4. Plants of the new Senecio have smaller inflorescences than         plants of ‘Sunsenegonana’.     -   5. Inflorescences of plants of the new Senecio have more ray and         disc florets than inflorescences than plants of ‘Sunsenegonana’.     -   6. Plants of the new Senecio differ from plants of         ‘Sunsenegonana’ in ray floret color as ray florets of plants of         the new Senecio are deep violet and light reddish purple in         color whereas ray florets of plants of ‘Sunsenegonana’ are dark         violet and pink in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Senecio plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Senecio plant.

The photograph at the top of the photographic sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘Sene Nirenago’ grown in a container.

The photograph at the bottom of the photographic sheet (FIG. 2 ) is a close-up view of typical inflorescences of ‘Sene Nirenago’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown during the late winter/early spring in 24-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Senecio production. During the production of the plants, day temperatures averaged 10° C. and night temperatures averaged 5° C. Measurements and numerical values represent averages for typical flowering plants. Plants were six months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
